We're dividing 78359574 by 574 
The aim is to understand the frequency of 574 in 78359574.

Step 1:
If we divide 7 by 574, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 574

On to step 2:
574 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 574

Let's proceed to step 3:
When dividing 783 by 574, we get 1 with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 574 from 783, we get 209.
Bring next digit (5) of the dividend behind the 209 and repeat the process: 2095 / 574

Going ahead to step 4:
If we divide 2095 by 574, we get 3 and a remainder of 373.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 373 after subtracting 1722 from 2095.
Append the next digit (9) from the dividend to 373 and continue with: 3739 / 574

Going ahead to step 5:
When dividing 3739 by 574, we get 6 with a remainder of 295.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Subtract 3444 from 3739 to get 295.
Fetch the next digit (5) from the dividend, attach it to 295 and continue: 2955 / 574

Let's proceed to step 6:
When dividing 2955 by 574, we get 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 1365.0
The remainder is 85 after subtracting 2870 from 2955.
Append the next digit (7) from the dividend to 85 and continue with: 857 / 574

Step 7:
857 divided by 574 is 1 with a remainder of 283.
Use 1 as the next digit of our solution. 
Result so far: 13651.0
Deduct 574 from 857 and we're left with 283.
Include the next digit (4) from the dividend after 283, then repeat: 2834 / 574

Advancing to step 8:
574 can be fit into 2834 4 times, resulting in a remainder of 538.
Record the quotient 4 as the next digit in the result. 
Result so far: 136514.0
The remainder is 538 after subtracting 2296 from 2834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 9:
574 goes into 5380 9 times with a remainder of 214.
Put 9 as the next digit of the answer. 
Result so far: 136514.9
The remainder is 214 after subtracting 5166 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 10:
574 goes into 2140 3 times with a remainder of 418.
Write down 3 as next digit of the result. 
Result so far: 136514.93
The remainder is 418 after subtracting 1722 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 11:
When dividing 4180 by 574, we get 7 with a remainder of 162.
Record the quotient 7 as the next digit in the result. 
Result so far: 136514.937
Deduct 4018 from 4180 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 12:
574 can be fit into 1620 2 times, resulting in a remainder of 472.
Record the quotient 2 as the next digit in the result. 
Result so far: 136514.9372
If we take 1148 away from 1620, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 13:
574 goes into 4720 8 times with a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 136514.93728
Subtract 4592 from 4720 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 14:
When dividing 1280 by 574, we get 2 with a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 136514.937282
The remainder is 132 after subtracting 1148 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 15:
The number 574 fits into 1320 2 times, leaving a remainder of 172.
The next digit of our result is 2. 
Result so far: 136514.9372822
Subtracting 1148 from 1320 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 136514.9372822, and the remainder is 1.72e-06.
